Application filed October 19,v 1922.V Seriall No. 595,702.

My invention relates to a fluid pressure device 'for the purpose of controlling the pressure supply and at the same timeop# erating an audible or visual signal to Warn .the attendant of abnormal pressure in the system- The object ofmy invention is to improve the construction ofthe pressure'controlled device itself and also to provide'improved supporting means and operating con# nections therefor.

In the accompanying drawings in which one form of my device is illustrated, Fig. 1 isa side elevation, the upper partzof the support being shown in section and a Jfragment p by a iiller block 6. Arranged in the centraly weight 28 is to return the stop member7 toy only of the alarm device being shown; Fig. 2 is a horizontal section, and Fig. 3 is an enlarged detail view showing the adjustable connection between oneuof the contactl arms and its operating lever. y

1 indicates a tubular support carried by a base 2. Secured to the support 1 at a. point intermediate of its length is a bracket 3 carrying a table 4 upon which' isv secured the pressure controlled device and. the alarm. The support l is divided into compartmentsl byfa pair of partition wallsf, spaced apart compartment is a stop member 7 described in a separate application. Attached to the lower n end of the stop member 7 is a cable v16 which passes downwardly, around a sheave 17, and lthence to any suitable valve control mecha-V.

nism.k 'A cable 26 is attached to the upper end of the'stop member 7 and extends upwardly over a sheave 27 and thence downwardly to a weight 28 in one of the lateral compart ments ofthe support. vThe purpose of this normal position. Y

. 30 is a central member carried by the table V4 vand having secured to it a pair of diaphragms 31. Secured centrally in each of Y y the diaphragms is a rod 32`sliding in a spider 33. The spiders33 vare secured to lugs on Vthe member 30. Coil springs 34 surround 1 c the rods 32 between the diaphragms 31 and the spiders 33. On the end of each of the rods32 is aV yoke 35 pivoted to an operating Y lever 36 and an equalizing lever 37. 38 are cross pieces secured tok brackets 39 on the member 30and1having pivoted to them the I centralparts of the'lever 30 and the ends of the levers 37. It will be understood that the pivot openings, either in the yoke orv Y,to permit the necessary ,movementsy levers 36 and 37v inustvbe slightly elongated.

This elongation, however, is so small ythat no attempt has been madeto show it in theV draw- ISES` ings. Pivoted `to the bracketsf39 are levers 40 connected by links `41with the levers 36.

42 are contact arms pivoted to the'levers 40xl ,at 43. One oii the arms'42 is adapted to acltuate the arm 13 by contact with its downturned end 15.` and the other to actuate the 4alarm device. Iny orderl that the arms 42 may be adjusted, the inner end of each is provided witha slot 45 concentric with the y pivot 43, through which slot passesa clampingscrew 44. Pressure is'admitted between the diaphragms through a pipe .49. Apressure gauge 50. is preferablyused to" assist in adjusting the device.

The operation of the device is as follows.

Pressure is admitted between the diaphragm 31' through the vpipe 49` and forces the said and ri`ormi'nga guide Vfor said rod', a 'springA I surrounding 'said rod between said diaphragm and spider, a yoke on saidy rod, a'V

'lever pivoted to one end'of said yoke, 'an equalizingbar-pivoted to the other end of said yoke, a control arm, and a link operatively connectingsaid lever to said control arm. 2.Iny a 'device of the class described, thek ksus combination with an annular member, of a diaphragm forming a side wall of said memf l bei' and carrying a rod, a spider supported from 'said member and formlng' abearingfor said rod, a coil spring surrounding said rod between said diaphragm and spider, a pair of oppositelyv disposed supports, and a lever system pivotally carried by said support an actuated from s aid rod. c
